Much of the information relating to individuals shown on the trees has been supplied by members of their respective families. It has not, however, been possible to trace the present-day representatives of a number of families, particularly the majority of those in Australia who are descended from Samuel Peek (1785-1860), third son of John Peek of Hazelwood. The biographical notes are by no means exhaustive, and mention is made therein only of those individuals about whom information has been contributed by themselves or their relatives or obtained from the various standard works of reference.
